NYAlertViewController is a replacement for UIAlertController/UIAlertView with support for content views and UI customization.

Features

• Includes content view property for adding custom views to the alert view
• Block-based API similar to UIAlertController/UIAlertAction
• Support for all screen orientations and iPad screen sizes
• Easily add text fields with simple API identical to UIAlertController
• Choose between fade (similar to UIAlertController) or slide transition animations

Usage Example

Objective-C

An Objective-C example project demonstrating customization options is included in the NYAlertViewControllerDemo directory.

// Import the class and create an NYAlertViewController instance
#import "NYAlertViewController.h"

// ...

// Set a title and message
NSString *title = @"Location Permission";
NSString *message = @"Set the alertViewContentView property to add custom views to the alert view";

// Customize appearance as desired
NYAlertViewControllerConfiguration *configuration = [NYAlertViewControllerConfiguration new];
configuration.contentViewInset = UIEdgeInsetsMake(12.0f, 8.0f, 8.0f, 8.0f);
configuration.alertViewBackgroundColor = [UIColor colorWithRed:0.23f green:0.23f blue:0.27f alpha:1.0f];
configuration.separatorColor = [UIColor colorWithRed:0.16f green:0.16f blue:0.2f alpha:1.0f];
configuration.titleTextColor = [UIColor whiteColor];
configuration.messageTextColor = [UIColor whiteColor];

configuration.buttonConfiguration = [NYAlertActionConfiguration new];
configuration.buttonConfiguration.titleColor = [UIColor whiteColor];

configuration.cancelButtonConfiguration.titleColor = [UIColor whiteColor];

// Set up alert actions
NYAlertAction *cancelAction = [[NYAlertAction alloc] initWithTitle:@"Later"
                                                             style:UIAlertActionStyleCancel
                                                           handler:nil];
NYAlertAction *okAction = [[NYAlertAction alloc] initWithTitle:@"Ok"
                                                         style:UIAlertActionStyleDefault
                                                       handler:^(NYAlertAction *action) {
                                                           [self doSomething];
                                                       }]];

NYAlertViewController *alertViewController = [[NYAlertViewController alloc] initWithOptions:configuration
                                                                                      title:title
                                                                                    message:message
                                                                                    actions:@[cancelAction, okAction]];

// Optionally add a content view
UIImageView *iconImageView = [[UIImageView alloc] initWithImage:[UIImage imageNamed:@"MapIcon"]];
iconImageView.contentMode = UIViewContentModeScaleAspectFit;
[iconImageView.heightAnchor constraintEqualToConstant:60.0f].active = YES;
alertViewController.alertViewContentView = iconImageView;

// Present the alert view controller
[self presentViewController:alertViewController animated:YES completion:nil];

alertViewController.alertViewContentView = iconImageView
    
// Present the alert view controller
self.present(alertViewController, animated: true, completion: nil)
